SEWING-MACHINE AUXILIARY.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed October 22, 1914. Serial No. 868,070. 2

To all whom it may concern Be it known that I, Josnrrr H. SorrAAr, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Sewing- Machine Auxiliaries; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in sewing machine auxiliaries,,and more particularly to means for facilitating the sewing of loops to straps,one object of the present invention being to provide a device for the purpose stated which shall be fixed to the work support of the machine and operate to press a loop back in such manner as to enable the stitching to be readily accomplished under the normal position of the loo 9.

l Vith this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating my improvements; Fig. 2 is a longitudinal sectional view, and Figs. 3 and t are views illustrating modifications.

1 represents the work support of a sewing machine, which support is shown in Fig. 1, of the arch form such as employed on machines of the Campbell type. This arch which covers the under-work of the machine, is formed near its center with an upward enlargement 2, one end of which is somewhat rounded and constitutes a stop or abutment to engage a loop on a strap and force the same backwardly and downwardly out of the way of the needle of the machine so that the stitching which secures the loop to the strap may be made under the normal position of the loop. In order to accommodate the loop on the strap when the same is being thus secured in place, the arch or work support is made with a recess 3. At the forward end of the stop or enlargement 2, the same is made with a ver tical groove 4 for the accommodation of the needle of the machine.

A throat plate 5 is located upon the stop or enlargement 2 and may be secured thereto in any suitable manner. This throat plate overhangs the recess 3 and is provided with a needle slot 6 which communicates with the vertical groove 4 in the end of the stop or enlargement 2.

In some types of machines, the work support is made flat instead of in the form of a transversely curved arch. For applica tion to such a machine, I may form the stop or enlargement 2 with or otherwise fix it to a base plate 7, as shown in Fig. 3, and in this construction the throat plate 5 may be either formed with or secured to the stop or enlargement 2.

In Fig. 4, the stop device 2 is shown as a separate piece which may be secured in any suitable manner to the work support, and if desired, a throat plate such as shown in Figs. 1 and 2 may be secured upon it.

Other slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. A sewing machine auxiliary, comprising an enlargement rising from the plane of the work plate and constituting an abutment at its forward end to engage a loop on a strap, said enlargement having a needle path rearwardly of said abutment, and a throat plate overhanging the abutment end of said enlargement and having an opening communicating with the needle path in said enlargement.

2. The combination with a sewing machine arch plate having a recess therein, of a loop stop fixed to and rising from said arch plate at one side of said recess and having a vertical needle groove, and a slotted throat plate located upon said loop stop and overhanging said loop stop and the recess in the arch plate.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
